Options and Accessories GPS-Time Synchronization Module Option 6 GPS-Time Synchronization Module Option This option consists of a GPS-receiver module including GPS antenna, and a 5 m connection cable for the Instrument 25-pole feature connector (on top of the instrument). Note For optimal performance the GPS receiver should be placed in a location where at least 4 satellites are within the receiving are; concrete, metal construction elements and roofs may interfere with, and reduce the GPS signal level.
1760 Users Manual garmin-settiings.bmp 2. Put the GPS receiver in a location with clear view to the sky. 3. Connect the GPS-receiver to the Instrument 25-pole feature connector on top. 4. Power on the Instrument. The instrument checks if there are NMEA data available. If yes it corrects the internal time. The internal time is taken for measurements. 5. The Pulse LED on the Instrument will start to blink at the reception of synchronization pulses. For LED functions see LEDs Time Sync.
